capturing the boston bombing suspect -- new details and video is your facing today, but when will officials get to start asking questions? and what more can we learn from the suspects as new information and pictures of their lives surface? the world's biggest marathon under way at this hour. a live report on security concerns there. in texas, for the first time some residents are getting back to their homes and scenes of remarkable devastation. hello, everyone. it's 7:00 a.m. in the east, 4:00

a.m. in the west. welcome it to "weekends with alex witt." massachusetts state police have released infrared footage of the capture of the boston marathon suspect, dozhokhar tsarnaev. this shows the cover being pulled off the boat and then an explosion from a flash grenade is seen going off. tsarnaev was captured shortly thereafter. the police chief of watertown, massachusetts, says he believes the two bombing suspects would have carried out more attacks if one wasn't killed and the other captured. i don't know for sure but my gut tells me, yes, if they have another pressure cooker bomb, they weren't saving that for the watertown police. they were saving that for another esevent similar to the boston marathon. i strongly believe that. >> massachusetts governor deval patrick says the 19-year-old suspect is in serious but stable condition at a boston hospital but likely cannot communicate yet. authorities say a special interrogation team for

high-value suspects will question him without reading him his miranda rights. we're getting a look at the suspect this morning, a video of tsarnaev, taken during a 2009 wrestling tournament. he's the one wearing the black wrestling uniform there. also, a congressional aide is telling the "boston globe" oversight committees are seeking intelligence or the lack thereof leading up to the boston marathon bombing. for more on the investigation i'm joined by nbc news national investigative correspondent michael isikoff. a good sunday morning to you, mi michael. what are we hearing about the time line when tsarnaev may be charged and the charges he is facing? >> reporter: well, we could see charges against tsarnaev as early as today. i know that federal prosecutors are were preparing them yesterday. actually, we've been told they might come late yesterday afternoon or even last night. they didn't. so it's possible we may now see them this morning. now what that would consist of is not an actual indictment but

a criminal complaint backed up by an affidavit most likely from an fbi agent that should have addition additional details about the evidence that the government hases on tsarnaev, where he bought the parts of the bomb, what actual -- we may learn where he purchased his weapons. other evidence that ties him direct directly to the bombing. and it could illuminate information we've all been looking for about how the bombs were made, when they were made, where they were made. we don't know how much the fbi knows at this point, but that's the kind of information that you often see in a criminal complaint of this kind. >> yeah. michael, i'm curious, what are we learning now about the fbi's prior look at the older brother who was killed, tamerlan tsarnaev? and is the fbi facing criticism is now? >> reporter: oh, yes. absolutely i think you're going to see an intense focus from capitol hill on this. and a lot of questions for the fbi. what we learned yesterday is

that the fbi did have prior information about the older brother, tamerlan, that the russian intelligence service had had asked the fbi to investigate him in 2011 saying he was a follower of radical islam. the fbi says they interviewed tamerlan. they questioned members of his family, looked into public databases, and concluded they had no evidence of -- no hard evidence of islamic activity. now what's interesting -- radical islamic activity or anything cripple nal. now what's interesting in january of 2012 he gets a visa, flies to russia for six months, stays there. then he comes back to the united states and within a month he opens up this youtube account that's filled with islamic jihadi postings and radical prophecies that clearly would indicate sympathies for the jihad cause. did the fbi even notice that

after having gotten this tip from the russian fsb? did they continue to monitor him? and then finally once the marathon bombing took place, did they go back right away to their databases and see what they had in their own files on radical extremists or possible radical extremists in the possible area and was there any information on tamerlan, did they notice the information they already had in their own files about tamerlan tsarnaev. >> and with regard it to the motive, michael, is there believed to be a chechen component there or the fact that chechen rebels and the defensemen on 0 stragss that have been more focused to moscow. it hasn't been faced to the west when they've been demonstrating. >> reporter: right. well, first of all, something cle clearly sparked the russians -- russian intelligence to send this notice to the fbi about tsarnaev. you know, a reasonable conclusion would be that it had some -- because they had some

information connecting him to chechen or radical extremists in central asia. that's all -- there are a number of radical extremist groups in that region, and the suspicious would be that he had some connection to that. but precisely what they were, we don't know. that's certainly one thing. how much the russians told the fbi is certainly one big piece of this puzzle. >> okay. michael isikoff, many thanks for that live report. well, as michael mentioned, the bombing investigation in part is shifting overseas today. this to the republic of dagestan where tamerlan tsarnaev visited in 2012. "the new york times" is reporting today that officialses are now, quote, scrambling to review that trip. it is a region of russia where their parents now live. more on the suspects' overseas connections. >> reporter: good day, alex. we're here on the street where the suspects' father owns an apartment and a shop he's been trying to sell.

the father hasn't been seen in about a day but we've been talking to some of the neighbors who say they're really surprised by everything that's happened. they have a hard time believing that the boston marathon bombings could have anything to do with this man, the father of the suspects. they describe him as a very good person, a good neighbor always ready with advice. the neighbors say they've never met the son including tamerlan. now dagestan is a small russian republic. it's in the north caucasus and it has had a tubled history especially in recent years where chechen militants have come across a porous border and brought their separatist attacks here. back to you, alex. >> adrienne mong, thank you for that. ongoing meetings to review the latest in the boston marathon investigation. and joining me now is nbc news white house correspondent peter alexander.

peter, a good sunday morning to you. big questions of whether or not dzhokhar tsarnaev will be charged as an enemy combatant. what do we know about where the white house is leaning? >> reporter: the white house is convinced the way this is being handled presently is the way it should be handled. that krcriticism about whether not tsarnaev should be handled as an enemy combatant is coming from republican lawmakers, john mccain and lindsey graham, kelly ayotte, and new york's representative, peter king. let's give you a accepts where this is right now. so law enforcement enacted basically an effort not to read tsarnaev his miranda rights. that means not telling him he has the right to remain silent under what they call the public safety exception, allows them to get as much information as they can within the immediate hours after his arrest. in case there is information about other plots or perhaps other accomplices but it's li

likely that he hasn't even been questioned yet because of his state, his serious condition, that this may not matter. he may have been read his miranda rights by a judge as early as tomorrow. the republican lawmakers, of course, say the public safety exception doesn't go far enough, that he should be treated as an enemy combatant. we do not want this suspect to have the right to remain silent. here is a little bit more about what they said. i'll put this graphic up on the screen. this is from a statement released by those republican lawmakers who say we have concerns limiting this investigation to 48 hours and exclusively relying on the public safety exception of miranda could very well be a national security mistake, they call it. they could severely limit our ability to gather critical information about future attacks from this suspect. alex? >> okay. thank you for that latest from the white house, peter alexander. some staggering numbers associated with the world's biggest marathon and a massive security effort trying to prevent another attack. we have a live report next.

an emotional return to fenway park in boston for red sox fans following the marathon bombings. security was certainly increased, but that didn't keep fans from packing the stands against the game with kansas city. the american flag was unveiled over the green mon 0ster to mass applause. fans joined with police officers and players to sing the national anthem and then shouted usa, usa. another big moment came when neil diamond led his "sweet caroline" in the eighth inning. >> what an honor it is for me to be here today. i bring love from the whole country. ♪ sweet caroline

♪ so good so good so good ♪ >> just awesome there. the bosox beat the royals, 4-3. now david ortiz, he made his season debut on saturday. he also addressed the crowd. let a little curse word slip as he told fans to stay strong. it does not look like he will face any fines. the fcc chairman tweeted this later in the day. david ortiz spoke from the heart at today's game. i stand with big papi and the people of boston. don't we all? the london mayrathon is goig on right now. the race is half a world away, runners laced up today with their minds on boston. we have details of the show of solidarity. duncan, to you. let's talk about how the organizers and the runners are honoring boston today. >> reporter: yeah, hi, alex. before the start of the race they took 30 seconds out for a moment of silence. many of the competitors stood there in silence with their

heads bowed, many wearing black ribbons in honor of the victims of boston. and then at the end of the 30 seconds there was some gentle applause and the race got under way. and since then, it's just been a normal london marathon. i've just come back down from the river thames. around half a million spectators are expected to be out lining the courses which winds its way around through some of london's biggest landmarks and in many ways, alex, i think perhaps that is the ultimate show of solidarity, just people coming out as normal, two good examples of that. we spoke to a couple who said when they saw what happened in boston they decided they weren't going to come down to london to watch the marathon, but then they said they saw the groundswell of support for the boston victims and they decided they should. and they told us they were having a great day but, of course, in the back of their minds there was some sadness thinking about what happened. and then another young couple,

some college students from slews, over here in london studying. they weren't really thinking about coming to watch the marathon. then when the bombings happened, they decided they should come out. they said that was their act of solidarity. alex? >> yeah, absolutely. you have to love that kind of support. but with regard to the security arrangements for spectators as well as the runners, that must have been a bit daunting to get through to where he they needed to go, right? >> reporter: yes. so what police have done, they have increased the police numbers by about 40%. that's around 700 officers across the 26-mile course. the police here have been really keen to say there is no change in the threat level, also no link to boston. what they're calling this is reassurance policing. more police possible on the streets. more sniffer dogs out, and they've taken a little bit of extra security with competitors' bags being careful the bags

aren't left around. really they say it's to make sure everyone feels safe and confident and enjoys the marathon as they have done every year. and having just come back from there, i think so far they have succeeded. >> and something to note considering how video cameras played such an important role in the investigation with the boston marathon, they added a few there in london and those are something that certainly would be looked at should anything go awry. duncan golestani, many thanks as always. from there to the weather. the midwest is experiencing major flooding as dozens of rivers overflow after a few days of heavy rain, and that includes the mississippi, which rose nearly ten feet in just 36 hours. these are some pictures. and look, it's not pretty at all there in indiana and also la grange, missouri. good morning to you. that's a cleanup mess. wow. and you know what, unfortunately in some areas in the midwest it's only going to get worse. the missouri rivers aren't expected to crest until about tuesday. so flooding is still going to be a major issue. temperatures, though, are actually helping the flooding

concern, the spring flooding concern he is peespecially up ae dakotas where temperatures right now are still close to freezing. and because we don't have a major warm-up in the forecast for areas like fargo, that should help with the snow melt. and so that it doesn't happen too rapidly and they can get a handle on some of the flooding before it gets too severe. in the midwest, though, chilly. temperatures below average across the entire northern tier of the country, even in the plains. normal highs in the low to mid-70s and we'll only be in the 60s this afternoon. there you see all those flood warnings posted all across michigan, wisconsin, down through i willinois and especia missouri we're kaepg an eye on for the potential of moderate to major flooding as we head into early next week. now we are seeing some showers redevelop especially back across iowa. unfortunately this is rain that that area does not need and it's not going to be too, too heavy but it's still more rain nonetheless so that is going to be an issue across iowa, eventually moving into wisconsin and northern illinois as well. temperatures today will be on

the cooler side, only in the 40s and 50s in the northeast. 50s and 60s across the midwest with more lighter showers moving in. snow is going to develop back through montana and the dakotas and we are looking for, again, those temperatures to stay on the cooler side as we head into most of next week but, again, we are going to keim an eye 0 out for the flooding as the rivers crest and then go above the flood stage and start to recede. this is going to be an issue he is pegs ly with more rain all throughout the week and then the spring thaw happens back through the dakotas as we get into the next couple of weeks. >> on a much lighter note, i wish it would have a spring feeling here. i went outside to leave for work this morning, i said, no! i had to go back in and get a coat. >> and you're ready to pack them up. >> not quite. thank you very much. i appreciate that, dylan dreyer. tragedy strikes twice in china. these pictures tell only part of the story.

the death toll in china

continues to rise following saturday's devastating 6.6 magnitude earthquake. just five years ago a massive quake in the same region killed nearly 70,000 people. joining me now from beijing with the very latest on this, ian, with a sobering good day to you. where do the numbers stand right now? >> reporter: alex, the number of dead has now gone over 200 with several thousand injured. there are reports in the chain he's press of villages flattened back in 2008 in that massive kuwait, quake, flattened again. some reports are still sketchy. rescue workers are still struggling to get to some of the more remote areas. their efforts hampered by la landslides on mountainous roads and also by aftershocks. there have been around 1,400 aftershocks. now the government has said thousands of soldiers in there.

we've seen images from the heart of the -- epicenter, if you like, where makeshift hospitals have been created partly to take the injured, to take those they pulled out of the rubble and partly to get people out of the hospita hospitals. there have been images of chinese's prime minister down there directing the operation. we've seen him in many different places. i think the government has been keen to show they're on top of this, that they have reacted speedily. they took some criticism five years ago after the '08 quake when the initial response was a little bit chaotic. don't forget, tens of thousands of people died in that quake. this time they want to give the impression of being quickly down there, to be on top of this disaster. now because of the nature of that area in the mountains, in the remote area, some of the information, some of the

casualty figures, are slow it to come out and do seem certain to rise, alex. >> it is an incredible rescue operation at this point as we saw dramatic pictures of people trapped in their homes. nbc's ian williams live in beijing. thank you for this update. we'll stay on top of this story here at msnbc. some residents are returning to their homes near a texas town rocked by a fertilizer explosion. cars formed a long line outside west, texas. residents and insurance agents were allowed in about a mile from the blast site. many of the homes were marked with a large red "x" indicating they were damaged beyond repair. >> i'm sitting like, i get to go home. yay. what am i going to go home to? how many other people do i know can't go home and they're not going to have anything, and am i going to have anything? and if i do, how am i going to feel if i have something others don't? is. >> 14 people killed, many houses destroyed in wednesday's

explosion. here is a frightening moment at a drag race near charlotte, north carolina. the engine exploding in a funny car saturday sending the fiberglass up into the air and right into the stands. two fans were treated for minor injuries. taking a look now at what's ahead on wall street. it is a make or break week for the stock market. around 170 s&p 500 and ten dow companies will be reporting their earnings. we are going to hear from apple, caterpillar, exxon, an unusually high number missed their estimates. we'll get a read on the gross domestic product for the first three months of the year. many analysts predict a sharp slowdown because of the millions in the federal spending cuts. and then how about a cool $2.5 million for a nickel. it is a rare liberty head nickel. it was mistakenly minted in 1913. it is expected to get at least that much at auction this week. it is one of only five known to
